I started with the card I already had in my computer and it was getting about a coin a day on 170 MH/s. Now I am running 1700 MH/s and getting only .12 per day. For the first year or so I was reinvesting the money in new hardware until I had 2000 MH/s. Then I started to cash out and am now up a couple grand. I haven't really kept track of the exact figures. I have not purchased any new hardware in over a year and am very impressed at the reliability of the video cards. I have one 6950 and 6 6770s and a 5750. The only card I had fail was a 5830 which is bad, because that card was a real money maker.
Thanks Blockhead, how much longer do you think you can mine Bitcoins before it is unprofitable with GPUs?
Not sure if I should start on some BTC before switching to LTC.
Did some LTC mining tests over the weekend on Nvidia cards but have AMDs on the way. Electricity is pretty expensive in Australia, I will make a small amount of money on LTC so it is mostly for the giggles (and hopes LTC does 1/10th as good as BTC).
